水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。

as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
